Anadromous, semi-anadromous, lacustrine, lacustrine-riverine, and riverine stocks have been reported. Most stocks are migratory, spending most of year at sea, sometimes rather far from coast (Ref. 59043). Stays mainly in the lower reaches of the rivers (Ref. 593) with slow current, large lakes and their tributaries, floodplain lakes, deltas and estuaries, marine waters with salinity up to 6-10%. Enters rivers in July - August and reaches spawning sites by October - November. In larger rivers, moves upriver up tp 2000 km (average speed 20 km/day). Spawns for the first time at 6-14 years, 47-50 cm SL. Spawns in rapids or shallows, at 1-2°C, when rivers start freezing. Adults leave spawning sites in winter (Ref. 59043). Eggs are buried in unguarded nests (Ref. 205). Eggs hatch in 150-180 days; peak hatching usually in April. Juveniles feed on plankton in winter (during which they do not cease active foraging) and benthic invertebrates in summer (Ref. 59043).
Status of threat: Important commercial species but rapidly declining (Ref. 59043).
Distinct pairing (Ref. 205).
